Quick Answer

Candidiasis of the skin is caused by yeast that thrives in warm moist environments, while a vaginal yeast infection, which is also the result of candida yeast, is caused by antibiotics, pregnancy, stress, a poor immune system or a hormonal imbalance, states Healthline. Candidiasis is a fungal infection that can affect many areas of the body, including the genitals, mouth, blood, throat and skin, explains WebMD.

Candidiasis is caused by a particular type of yeast, most often the Candida albicans strain, according to WebMD. While it is normal for small amounts of this yeast to be present on the human body, an overgrowth caused by certain medications or health issues can lead to unpleasant or dangerous health problems. A candidiasis overgrowth in the mouth or throat area is called thrush, while candidiasis in the blood is referred to as candidemia or invasive candidiasis.

Thrush typically affects infants, the elderly, people with weakened immune systems or those receiving chemotherapy, states WebMD. Oral antifungal medication is prescribed to kill the yeast, but severe cases may require the use of a very strong intravenous antifungal medicine. While most vaginal yeast infections respond to a three-day antifungal regime, some types are resistant to normal treatment. In this case, a treatment lasting 14 days to six weeks may be required, along with the use of condoms during intercourse and treatment for the partner.
